Young Ireland (Irish: Éire Óg, IPA: [ˈeːɾʲə ˈoːɡ]) was a political, cultural and social movement of the mid-19th century. It led changes in Irish nationalism, including an abortive rebellion known as the Young Irelander Rebellion of 1848. Many of the rebellion's leaders were tried for sedition and sentenced to penal transportation to Van Diemen's Land. From its beginnings in the late 1830s, Young Ireland grew in influence and inspired following generations of Irish nationalists.
